The communtative property chages the grouping
Answer: w=−xy+x/y
Step-by-step explanation:
Let's solve for w.
w=
x
y
−x
Step 1: Multiply both sides by y.
wy=−xy+x
Step 2: Divide both sides by y.
wy
y
=
−xy+x
y
w=
−xy+x
y
Not enough information. The question doesn't say how much one quart of paint covers.
EDIT: here's the solution
we have to find the total area of the 4 walls and subtract the area of the door. there are 2 walls with dimensions 16 by 10, and 2 walls with dimensions 16 by 12. so we have: 2(16*10)+2(16*12)=320+384=704 for the area of the walls. now, we can find the area of the door which is 3*8=24. <span>so we subtract the area of the door from the area of the walls, so we have: 704-24=680. </span><span>Since a quart of paint covers 100, then we divide and get 680/100=6.8 but since we need a whole number of quarts, we round up to get 7 quarts of paint. </span>
